League of Legends patch 12.15 complete preview: All expected changes, release date, and more

League of Legends patch 12.15 is scheduled to go live sometime next week, and Riot Games has a fair bit of updates planned for the upcoming update.

While 12.15 will not be completely upsetting the current champion meta, it will, however, introduce a fair bit of tweaks to smoothen things out for some of the champions in the game.

One of the update's most significant highlights will be the buffs that energy champions will receive. Hence, Akali, Shen, Zed, Kennen, and Lee Sin will receive many quality-of-life updates.

Additionally, Master Yi and Sivir will be in for some nerfs. Only recently did the two champions see a significant number of tweaks make their way to their kit. However, they will be toned down quite a bit in League of Legends patch 12.15.
